"South Asia has not competed with other regions yet"
Yeah, that will happen when you give them slots.
"South Asia is new"
Pretty much every big CSGO pro got access to Valorant Beta and many switched from day 1 of release. There have been tournaments and fully paid professional teams since the beginning of Valorant. There is good viewership. Good participation. What else do you want?
Also, don't forget that the first year is literally the most important year of growth for any region.
There was so much interaction around Valorant in South Asia this year, seeing Riot's attitude and hardly any future for Valorant in India, atleast 3 big orgs have released their teams. South Asia is already 25% dead region at this point.
